Hey all,

I recently purchased a lifted 2010 Wrangler Sport. Felt a little unstable on the highway (not in a death wobble kind of way), so I took it to first get aligned to establish a baseline understanding. Firestone was able to align just about everything except the caster (1.9 degree on left and 2.3 degree on right - camber on L and R both at -0.6). They said they could not align the caster due to a plate mechanism that was installed and instead recommended acquiring a caster/camber adjustment kit or eccentric adjusters. They were unable to source them but offered to install/fix/align if I were able to source the equipment. Would anyone happen to have recommendations on where to find these? Thanks!

 

Take pics of jeep control arms for us on axle and frame sides so we can see what you're working with. I am pretty sure they are referring to cam bolts with the term eccentric adjusters. I would not use cam bolts at all, and with caster that low, they're not going to help enough even if you did. You should consider adjustable control arms or control arm brackets. Caster that low is going to have a big effect on some crappy steering so that is likely what you're noticing.

 

Stay away from cam bolts, depending what is installed on your Jeep, either adjustable control arms as Resharp suggested will help or possibly geometry correction brackets.

 

Thanks for the replies - I appreciate the help! I’ve attached some pics of the control arms. Let me know what y’all think.

 

y, you have zero caster correction right now. It looks like that front axle likely had cam bolts at one point cuz those metal rectangles under the bolts should be cam bolt eliminators to take up the hole the cam bolts needed. control arm brackets or adjustable control arms are going to be your path. If you don't plan to wheel in big rocks, there is nothing wrong with control arm brackets. Get ones that have multiple mounting options though if you go that route.

 

thanks again for the reply - where would you find the control arm brackets?

 

The Rancho set is a nice 1-piece design that offers 4 mounting positions -



They cost a little more than the others but are nice. AEV makes some, as does Rubicon Express, and i think those are closer to $100 but are a little more cumbersome to install. These are items that could always be removed and resold in the future so keep that in mind. If the jeep is primarily going to be on pavement or light trails the brackets are going to provide a better ride quality as they lower the frame side mount of the arm, and flattening the angle of the control arm will equate to more comfort. Though you can adjust caster with adjustable control arms, the angle the arms run from frame to axle remains sharp so the ride is typically a touch rougher, but the trade off is not loosing any ground clearance at the frame when wheelin in big rocks.

 

Great description on what geo brackets do and control arms!!
